Abstract:
The membrane produced was imposed by two rheological factors, which applied
with different coagulation bath temperature at 10 °C, 30 °C, and 50 °C and different
forced convection resident time which was at 10 s, 15 s, and 20 s. Tho objective of
this study is to investigate the effect of those rheological factors to the steric and
charges on the separation performance and fine structural details of UF membranes.
By using the same composition, an uncertainty imposed by the membrane material
upon separation performances can be eliminated. The membrane is fabricated using a
ternary dope formulation of 14.4% Polysulfon_e (PSF), 81.6% N-methyl-2
pyrrolidone (NMP), and 4% water by a dry/wet phase inversion process using an
electrically controlled flat sheet membrane casting machine.
